Demographic, neuropsychological, and speech variables that impact iconic and supplementary-to-speech gesturing in
aphasia
We model the role of demographic, neuropsychological and speech variables in characterizing iconic gesture use in
speakers with aphasia, especially gestures that supplement speech and are essential for understanding the spoken message. Using
backward regression modelling with cross validation in 37 speakers with aphasia, literature-derived demographic (e.g., age),
neuropsychological (e.g., aphasia and anomia severity), and speech (e.g., speaking duration) variables were used to predict
frequency and rate (per minute) of iconic, supplementary, and essential gesturing. We identified that nearly 60% of iconic
gestures produced by speakers were supplementary to speech with 38% being essential for understanding the speech. Generally, those
with more severe aphasia, anomia, and with nonfluent aphasia tended to produce fewer tokens and a slower rate of speech, and these
were the speakers who produced more and a higher rate of supplementary and essential gestures. These findings underline the
importance of iconic gestures to improve communication.
期刊介绍:
Gesture publishes articles reporting original research, as well as survey and review articles, on all aspects of gesture. The journal aims to stimulate and facilitate scholarly communication between the different disciplines within which work on gesture is conducted. For this reason papers written in the spirit of cooperation between disciplines are especially encouraged. Topics may include, but are by no means limited to: the relationship between gesture and speech; the role gesture may play in communication in all the circumstances of social interaction, including conversations, the work-place or instructional settings; gesture and cognition; the development of gesture in children.
